A method for allocating correction values of the degree of bending of a substrate (2) relative to a coordinate system (40) of a coordinate measuring machine (1) is disclosed. The positions of the at least two reference marks (32) on the substrate holder (27) are automatically determined relative to the coordinate system (40) of the coordinate measuring machine (1) for each substrate (2) currently placed in the substrate holder (27) in the coordinate measuring machine (1).
摘要:
A method of detecting incomplete edge bead removal from a disk-like object is disclosed. First a peripheral area of a disk-like reference object is imaged. Marks are then defined in the peripheral area of the reference object. Finally, images of peripheral areas of a plurality of disk-like objects of the same batch are recorded. The inspection of the disk-like objects is limited to the locations of the marks defined on the reference object.

A device 1 is disclosed for inspecting, measuring defined structures, simulating structures and structural defects, repair of and to structures, and post-inspecting defined object sites on a microscopic component 2 with an immersion objective 8a. The device 1 comprises a stage that is movable in the x-coordinate direction and in the y-coordinate direction and a holder 42 for the microscopic component 2, whereby the holder 42 is placed on the stage 4 with the microscopic component 2 in it. The holder 42 has a reservoir 51a with immersion or cleaning fluid, respectively. The stage 4 is movable such that the immersion objective 8a is located directly above the reservoir 51a and may dip into the fluid with its front-most lens.
摘要:
A method of visualizing measuring values from recorded images of disk-like objects is disclosed. First an image is recorded of at least one disk-like object, and a great number of measuring values is generated. Each measuring value is associated with a color value. Finally a resulting image is generated wherein an area which has resulted in a measuring value on the disk-like substrate is associated with a color value selected from a predetermined palette.
摘要:
The invention concerns an apparatus for inspection of a wafer, encompassing at least one illumination device in order to radiate an illuminating light beam onto a surface of the wafer, and an image capture device in order to capture an image of an illuminated region on the surface of the wafer in a plurality of spectral regions, a color modification device being provided in order to modify the color spectrum of the illuminating light beam or of the reflected light beam. The wafer inspection apparatus is characterized in that the color modification device is designed in such a way that the color spectrum of the illuminating light beam, or that of the image that is acquired of the surface of the wafer, is adaptable to the spectral sensitivity of the image capture device.

The invention relates to a substrate support apparatus (41) for use in a position measuring device (1) for determining the position of a substrate (30, 45) supported by the substrate support apparatus (41) by means of a laser interferometer system (29), wherein the substrate support apparatus (41) comprises a traversable stage construction (26, 42), and a stage mirror (9, 43) fixedly associated with the stage construction for reflecting a laser beam of the laser interferometer system, wherein it is suggested that the measurement-critical components, associated in a spatially fixed way, of the substrate support apparatus (41) in the combination of elements ranging from the stage mirror (9, 43) to the substrate (30, 45) are of material structures having moduli of elasticity which differ from that of the substrate (30, 45) by not more than 15%. As a result, the negative effects of air pressure fluctuations on the laser-interferometric position measurement can be greatly reduced.
